ABSTRACT

Introdução: Por sua posição na face, a mandíbula é frequentemente atingida pelos traumas, surgindo em algumas estatísticas como o osso fraturado com maior incidência em face. Em fraturas de mandíbulas atróficas o tratamento conservador, com fixação intermaxilar não costuma ser uma opção viável pela falta de dentes e pequena área de contato ósseo existente. Dessa forma, a redução aberta e fixação interna estável tem sido o tratamento de escolha sempre que a condição do paciente permitir. Objetivo: relatar um caso de osteossíntese de fratura de mandíbula atrófica por acesso extraoral. Relato de caso: Paciente 64 anos, faioderma, sexo feminino, procurou o serviço de Cirurgia e Traumatologia Bucomaxilofacial da Universidade Federal da Bahia apresentando traumatismo facial por queda da própria altura, referindo severas queixas álgicas espontâneas em região mandibular. Ao exame físico notou-se edentulismo total em ambas as arcadas, edema, hematoma e degrau ósseo á palpação em região de corpo de mandíbula a direita, alémde mobilidade atípica a manipulação da mandíbula. Ao exame de imagem notou-se sinais de fratura em corpo mandibular direito e côndilo esquerdo. O tratamento instituído foiconservador para a fratura de côndilo e cirúrgico para a fratura de corpo, o acesso foi extraoral ea fixação rígida foi realizada com placa e parafusos dos dispositivos Load-Bearing. Considerações finais: A paciente não apresentou quaisquer déficits funcionais pós-procedimento cirúrgico, sendo o tratamento abertocom fixação interna estável bastante promissor por restabelecer a união de focos fraturados e deslocados, proporcionando estabilidade da fratura e conforto imediato para a paciente(AU)


Introduction: Due to its position on the face, the jaw is frequently affected by trauma, appearing in some statistics as the fractured bone with a higher incidence in the face. In fractures of atrophic jaws, conservative treatment, with intermaxillary fixation, is not usually a viable option due to the lack of teeth and small area of existing bone contact. Thus, open reduction and stable internal fixation have been the treatment of choice whenever the patient's condition permits. Objective: to report a case of osteosynthesis of atrophic mandible fracture through extraoral access. Case report: Patient 64-year-old, female, sought the service of Maxillofacial Surgery and Traumatology at the Federal University of Bahia presenting facial trauma due to falling from his own height, referring to severe spontaneous pain complaints in the mandibular region. On physical examination, total edentulism was noted in both arches, edema, hematoma and bone step on palpation in the right jaw body region, in addition to atypical mobility in the jaw manipulation. On imaging examination, signs of fracture were noted in the right mandibular body and left condyle. The treatment instituted was conservative for condyle fracture and surgical for body fracture, access was extraoral and rigid fixation was performed with plate and screws of the Load-Bearing devices. Final considerations: The patient did not presente any functional deficits after the surgical procedure, and the open treatment with stable internal fixation is very promising for restoring the union of fractured and displaced foci, providing fracture stability and immediate comfort for the patient(AU)

El objetivo de este trabajo es mostrar los resultados clínicos y radiológicos del tratamiento de las fracturas diafisiarias de tibia con osteosíntesis mínimamente invasiva con placa por cara lateral. Se realizó un estudio clínico observacional, prospectivo, longitudinal y no concurrente. Se incluyeron pacientes mayores de 18 años, de ambos sexos, con diagnósticos de fracturas diafisiarias de tibia 42A, 42B ó 42C, abiertas o cerradas. Se estableció tiempo de seguimiento mínimo de 6 meses. Se incluyeron 23 pacientes, 82,60% de sexo masculino. Promedio de edad de 21±5,63(16­49) años. La fractura más frecuente fue la 42B2 en 26,00% de los casos, y 34,80% fracturas fueron abiertas. A las 12 semanas, 65,10% habían alcanzado consolidación Montoya III; y para la semana 16, 91,30% de los pacientes. De acuerdo a la escala ASAMI, se alcanzaron resultados excelentes en 100,00% pacientes para la semana 16. No se presentaron complicaciones como infección, aflojamiento séptico o aséptico del implante, ni fatiga del mismo. El uso de la técnica MIPO para tratamiento de fracturas diafisiarias de la tibia, por cara lateral es una técnica efectiva y segura, con alta tasas de consolidación, mínimas complicaciones y buenos resultados finales(AU)


Minimally invasive surgical techniques help the natural bone healing process to occur, by providing enough biomechanical stability to obtain the best results. The objective is to show the clinical and radiological results of the treatment of diaphyseal tibial fractures with minimally invasive osteosynthesis with lateral plating. An observational, prospective, longitudinal and non-concurrent clinical study was made. Patients older than 18 years, both sexes, with diagnoses of open or closed tibial shaft fractures 42A, 42B or 42C, were included. A minimum follow-up time of 6 months was established. 23 patients were included, 82,60% male. Average age of 21 years. The most frequent fracture was 42B2 in 26,00% cases, and 34,80% were open fractures. At 12 weeks, 65,10% had reached Montoya III consolidation criterias; and for week 16, 91,30% of the patients. According to the ASAMI scale, excellent results were achieved in 100,00% patients. There were no complications such as infection, septic or aseptic loosening of the implant, or fatigue of the implant. The use of the MIPO technique for the treatment of diaphyseal fractures of the tibia on the lateral aspect is an effective and safe technique, with high rates of union, minimal complications and good final results(AU)

ABSTRACT

Abstract Objective The present study aims to analyze the clinical results of the surgical treatment of metacarpal neck fractures with retrograde intramedullary fixation using cannulated headless screws (Herbert type). Methods Retrospective study of 21 closed fractures deviated from the metacarpal neck in 21 patients operated between April 2015 and November 2018. Results The sample included 19 men and 2 women. The mechanisms that caused the trauma were punching, falling to the ground and motor vehicle accident (n = 14, 5 and 2). The affected metacarpals were the 5th, 3rd, and 2nd (n = 19, 1 and 1). Surgical indications were neck-shaft diaphysis of the metacarpal > 30º for the 2nd and 3rd metacarpals and > 40º for the 5th metacarpal, shortening ≥ 5mm, rotational deviation, and the desire of the patient not to use plaster cast. In the immediate postoperative period, patients remained without immobilization and were instructed to mobilize their fingers according to tolerance. All patients had total active mobility > 240º and returned to their former occupations. All fractures consolidated and there were no reinterventions. Discussion The great advantages of the headless screw technique are its low morbidity, sufficient stability to avoid external immobilization, and reproducibility at low cost. Conclusion This is an easy, fast technique that has excellent results for the surgical treatment of displaced fractures of the neck of the metacarpals.


Resumo Objetivo O presente estudo visa analisar os resultados clínicos do tratamento cirúrgico das fraturas de colo do metacarpo com fixação intramedular retrógrada utilizando parafusos canulados sem cabeça (tipo Herbert). Métodos Estudo retrospectivo de 21 fraturas fechadas desviadas do colo do metacarpo em 21 pacientes operados entre abril de 2015 e novembro de 2018. Resultados A casuística incluiu 19 homens e 2 mulheres. Os mecanismos causadores do trauma foram soco, queda ao solo e acidente com veículo motorizado (n = 14, 5 e 2). Os metacarpos acometidos foram o V, III e II (n = 19, 1 e 1). As indicações cirúrgicas foram angulação colo-diáfise do metacarpo > 30º para os II e III metacarpos e > 40º para o V metacarpo, encurtamento ≥ 5mm, desvio rotacional e o desejo do paciente de não utilizar imobilização gessada. No pós-operatório imediato, os pacientes permaneceram sem imobilização e orientados a mobilizar os dedos conforme tolerância. Todos os pacientes ficaram com mobilidade ativa total > 240º e retornaram às suas antigas ocupações. Todas fraturas consolidaram e não houve reintervenções. Discussão As grandes vantagens da técnica com parafuso sem cabeça são sua baixa morbidade, estabilidade suficiente para não precisar de imobilização externa e reprodutibilidade com baixo custo. Conclusão Esta é uma técnica fácil, rápida, e que apresenta ótimos resultados para o tratamento cirúrgico das fraturas deslocadas do colo dos metacarpos.

ABSTRACT

INTRODUCCIÓN: Una de las complicaciones de la osteosíntesis retrógrada del escafoides es la protrusión del tornillo en la articulación radiocarpiana, dada la limitada visualización intraoperatoria del polo proximal del escafoides con las proyecciones tradicionales. OBJETIVO: Evaluar la capacidad de una nueva proyección radiológica, la proyección "tangencial del escafoides dorsal", o TED, para identificar tornillos prominentes radiocarpianos durante la osteosíntesis retrógrada del escafoides con tornillos canulados. MATERIALES Y MÉTODOS: Estudio cadavérico en muñecas frescas congeladas. Se introdujo en el escafoides un tornillo canulado con técnica retrógrada estándar. La proyección TED fue evaluada en 5 muñecas, con angulaciones del antebrazo de 15°, 30° y 45° para definir la mejor visualización del polo proximal del escafoides y del tornillo. Se comparó la capacidad para identificar la prominencia del tornillo en el polo proximal de la proyección TED de 30° con 5 proyecciones tradicionales de escafoides en 9 muñecas. El tornillo se posicionó a nivel de la superficie del escafoides, y luego se avanzó a intervalos de 0,5 mm bajo visualización directa por artrotomía dorsal. Tras cada intervalo, se repitieron todas las proyecciones para determinar su capacidad de detectar tornillos prominentes en el escafoides. RESULTADOS: La mejor visualización del polo proximal del escafoides se logró con la proyección TED de 30°. Al comparar la proyección TED de 30° y las tradicionales, con la TED se logró identificar tornillos prominentes a 0,8 mm promedio, seguida por la proyección posteroanterior con cubitalización y extensión a 1.3 mm (p » 0.014), con una alta precisión y correlación interobservador de estas proyecciones. CONCLUSIÓN: La proyección TED demostró ser la más sensible para detectar tornillos prominentes en la articulación radiocarpiana. Su uso rutinario podría evitar complicaciones durante la osteosíntesis.


INTRODUCTION: One of the complications of the retrograde percutaneous scaphoid fixation is the protrusion of the screw in the radiocarpal joint due to the limited intraoperative visualization of the proximal pole of the scaphoid with the traditional radiographic views. OBJETIVE: To evaluate the sensitivity of a novel radiographic view (the skyline scaphoid view, SSV) to detect screws protruding in the radiocarpal joint during the retrograde fixation of the scaphoid. MATERIALS AND METHODS: We studied nine cadaverous fresh frozen wrists. A retrograde cannulated screw was inserted in the scaphoid. To validate the SSV, 5 wrists were studied, comparing 3 forearm angulations (15°, 30° and 45°) to get the best visualization of the proximal pole and screw. We compared the ability to identify the protrusion of the screw in the proximal pole of the 30° SSV with that of 5 standard scaphoid radiographic views in 9 wrists. The screw was positioned at the level of the surface of the scaphoid, and was sequentially protruded in 0.5 mm increments, with direct visualization of its tip through a dorsal capsulotomy. After each increment, all views were repeated to determine if they were able to detect screws projecting from the scaphoid. RESULTS: The best visualization of the proximal pole of the scaphoid was found with the 30° SSV. In the comparison of the 30° SSV and the standard views, with the SSV we were able to identify the protrusion of the screws at an average of 0.8 mm, followed by the posterior-anterior view with ulnar deviation and extension at 1.3 mm (p » 0.014), with high precision and interobserver agreement regarding these views. CONCLUSION: The SSV was the most sensitive view to detect protruding screws in the proximal pole of the scaphoid. Its routine use could avoid complications during osteosynthesis.

ABSTRACT

Los fragmentos posterolaterales (FPLs) en fracturas de platillo tibial son frecuentes, pero difíciles de reducir y estabilizar. Actualmente existe controversia sobre cómo deben ser abordados; si bien un abordaje anterolateral es más seguro, este puede ser insuficiente para lograr una correcta reducción. Los abordajes posterolaterales y posteriores ofrecen una visión directa y permiten una fijación con ventaja biomecánica; sin embargo, son más demandantes y exponen al paciente a una mayor morbilidad. A continuación, se presenta una nota técnica sobre la reducción y fijación de FPLs con una placa rim por medio de un abordaje anterolateral extendido a través del espacio paraligamento colateral lateral.


Posterolateral fragments (PLFs) are commonly seen in tibial plateau fractures, but their reduction and fixation are challenging. There is no consensus about the ideal approach to fix this particular fragment. Even though an anterolateral approach is a safe option, it may impair a correct reduction. The posterolateral and posterior approaches offer direct visualization of the fragment, and enable a fixation with a biomechanical advantage; however, they are more demanding and expose the patient to a higher risk if morbidity. The following technical note describes the reduction and fixation of PLFs with a rim plate through an extended anterolateral approach using the paralateral collateral ligament space.

ABSTRACT

Abstract The method presented here consists of a minimally invasive surgical technique for osteosynthesis of transtrochanteric fractures with Dynamic Hip Screw (DHS) 135º. It is indicated in the treatment of 31-A1 and 31-A2 fractures (Arbeitsgemeinschaft für Osteosynthesefragen Classification - AO) that meet the prerequisites required for using DHS. The surgery is performed, preferably, before 48 hours after the fracture. With the use of the same instruments as the traditional surgical technique and the aid of the C-arm, a closed reduction of the fracture and implantation of the DHS is performed by a 2-cm surgical incision, through dissection of the underlying tissues, with minimal bleeding and damage to the soft parts. In the immediate postoperative period, the patient is encouraged to orthostatism and walk with full load, which anticipates hospital discharge and favors early functional rehabilitation. Outpatient return is scheduled at 2, 6, 12 and 24 weeks postoperatively, with radiographic evaluation to assess fracture healing.


Resumo O método aqui apresentado consiste em técnica cirúrgica minimamente invasiva para osteossíntese de fraturas transtrocantéricas com Dynamic Hip Screw (DHS) 135º. Esta técnica é indicada no tratamento de fraturas 31-A1 e 31-A2 (Classificação Arbeitsgemeinschaft für Osteosynthesefragen - AO) que cumpram os pré-requisitos exigidos para o uso do DHS. A cirurgia é realizada, preferencialmente, antes de 48 horas após o acometimento da fratura. Com a utilização do mesmo instrumental da técnica cirúrgica tradicional e auxílio do arco-C, realiza-se redução incruenta da fratura e implantação do DHS por incisão cirúrgica com 2 cm, através de dissecção dos tecidos subjacentes, com mínimo sangramento e agressão às partes moles. No pós-operatório imediato, o paciente é estimulado ao ortostatismo e à deambulação com carga total, o que antecipa a alta hospitalar e favorece a reabilitação funcional precoce. O retorno ambulatorial é agendado com 2, 6, 12 e 24 semanas de pós-operatório, com avaliação radiográfica, a fim de avaliar a consolidação da fratura.

ABSTRACT

BACKGROUND@#The open reduction and internal fixation (ORIF) was a standard treatment approach for fracture at distal humerus intercondylar, whereas the optimal way before ORIF remains inconclusive. We, therefore, performed a systematic review and meta-analysis to assess the efficacy and safety of olecranon osteotomy vs. triceps-sparing approach for patients with distal humerus intercondylar fracture.@*METHODS@#The electronic searches were systematically performed in PubMed, EmBase, Cochrane library, and Chinese National Knowledge Infrastructure from initial inception till December 2019. The primary endpoint was the incidence of excellent/good elbow function, and the secondary endpoints included Mayo elbow performance score, duration of operation, blood loss, and complications.@*RESULTS@#Nine studies involving a total of 637 patients were selected for meta-analysis. There were no significant differences between olecranon osteotomy and triceps-sparing approach for the incidence of excellent/good elbow function (odds ratio [OR]: 1.37; 95% confidence interval [CI]: 0.69-2.75; P = 0.371), Mayo elbow performance score (weight mean difference [WMD]: 0.17; 95% CI: -2.56 to 2.89; P = 0.904), duration of operation (WMD: 4.04; 95% CI: -28.60 to 36.69; P = 0.808), blood loss (WMD: 33.61; 95% CI: -18.35 to 85.58; P = 0.205), and complications (OR: 1.93; 95% CI: 0.49-7.60; P = 0.349). Sensitivity analyses found olecranon osteotomy might be associated with higher incidence of excellent/good elbow function, longer duration of operation, greater blood loss, and higher incidence of complications as compared with triceps-sparing approach.@*CONCLUSIONS@#This study found olecranon osteotomy did not yield additional benefit on the incidence of excellent/good elbow function, while the duration of operation, blood loss, and complications in patients treated with olecranon osteotomy might be inferior than triceps-sparing approach.

ABSTRACT

OBJECTIVE@#To analyze and compare the clinical efficacy of different types of surgical treatment of periprosthetic femoral fracture(PFF) after hip arthroplasty (HA).@*METHODS@#From September 2010 to September 2016, 47 patients (47 hips) with periprosthetic fractures after total hip arthroplasty were retrospectively analyzed, including 13 males and 34 females. According to Vancouver classification, there were 2 patients with type AG, 17 patients with type B1, 19 patients with type B2, 7 patients with type B3 and 2 patients with type C. The age of patients ranged from 56 to 94 (71.5±8.3) years. After admission, nutritional risk screening (NRS2002) was used to assess the nutritionalstatus of the patients. Eighteen patients (38%) had malnutrition risk (NRS>3 points). After admission, the patients were given corresponding surgical treatment according to different types. Intraoperative blood loss was recorded. Harris score was used to evaluate the hip function. VAS pain score was performed on admission and after operation.@*RESULTS@#All the 47 patients were followed up for 19 to 62 (34±11) months. The Harris scores were (41.8±12.1) and (89.0±2.6) respectively before and 1 year after operation, and the difference was statistically significant (@*CONCLUSION@#The treatment of hip periprosthetic fracture patients should be based on the general situation of patients, imaging data, intraoperative correction classification, etc. to develop individualized treatment plan in line with patients. For patients with preoperative malnutrition risk, preoperative nutritional intervention may reduce intraoperative bleeding.

ABSTRACT

OBJECTIVE@#To measure the maximum corridor parameters of the infra acetabular screw and evaluate the feasibility of screw insertion through digital analysis of the acetabular structure.@*METHODS@#The pelvic CT data of 100 patients who received plain pelvic CT scan from April 2013 to June 2015 were retrospectively analyzed. There were 50 males, aged 20 to 84 years, with an average age of (48.42±17.48) years, and 50 females, aged 18 to 87 years, with an average age of (55.02±19.54) years. Patients with acetabular fractures, hip dysplasia, and metal implants in the acetabulum were excluded. Import CT data into Mimics software in DICOM format to generate a three-dimensional model, and find the axialprojection of the infra-acetabular corridor in the middle of the pubis ramus in the inlet view. A virtual screw was placed in the infra-acetabular space and measure the parameters including the diameter and the length of the maximum corridor, the distance from the insertion point to the pubic symphysis, to the anterosuperior iliac spine and to the medial edge of the pelvis. Then import the pelvic model into 3- matic software, establish the pelvic model anterior pelvic plane and median sagittal plane, and measure the angle between the screw axis and the two planes. A minimum corridor diameter of at least 5 mm was defined as a cutoff for placing a 3.5 mm screw, and calculate the screw insertion rate.@*RESULTS@#In 100 cases, 49% of patients had a infra acetabular corridor with a diameter ≥5 mm, and the rate of screw placement in men was significantly higher than that in women. The average diameter of the maximum corridor of infra-acetabular screw was (4.86±1.72) mm, the average length was (94.04±8.29) mm, the average distance from the insertion point to the pubic symphysis was (60.92±4.84) mm, to the anterosuperior iliac spine was (85.15± 6.85) mm, and to the medial edge of the pelvis was (6.12±3.32) mm. The mean angle between the axis of the screw and the median sagittal plane was (-1.38±4.74)°, and the mean angle between the axis of the screw and the anterior pelvic plane was (56.77±7.93)°. There are significant differences between male and female measured parameters, except for the angle between the screw axis and the anterior pelvic plane. There was no statistically significant difference in the maximum corridor parameters of infra-acetabular screw on both sides of the pelvis.@*CONCLUSION@#This study shows that the insertion rate of infra-acetabular screws is low in local patients, and the feasibility of screw insertion should be fully evaluated before surgery.

ABSTRACT

OBJECTIVE@#To study the relationship between osteonecrosis of femoral head after internal fixation of femoral neck fracture and serum bone metabolism, vascular active factors, and analyze the risk factors.@*METHODS@#Total 150 patients with femoral neck fracture who underwent reduction and internal fixation from April 2016 to April 2019 were selected, including 83 males and 67 females. According to whether there was necrosis of femoral head after operation, they were divided into necrosis group(32 cases) and non necrosis group (118 cases). Before operation and 1, 3, 5 days after operation, the serum levels of beta-C terminal cross-linked telopeptides of typeⅠ collagen(β-CTX), N-telopeptide of typeⅠ procollagen(PINP), nitric oxide (NO), Endothelin-1 (ET-1) were measured. The clinical characteristics of the two groups were compared. The risk factors of postoperative femoral head necrosis were analyzed by logistic regression model. The value of serum indexes in predicting postoperative femoral head necrosis was analyzed by ROC curve.@*RESULTS@#There was no significant difference in the levels of serum PINP and β-CTX between necrotic group and non necrotic group before operation and 1, 3 and 5 days after operation(@*CONCLUSION@#The content of serum NO and ET-1 on the first day after operation can predict the necrosis of femoral head.

ABSTRACT

OBJECTIVE@#To retrospectively analyze the clinical efficacy of external fixation in the treatment of femoral neck fracture with two different pin layout.@*METHODS@#From April 2000 to April 2018, 140 cases of femoral neck fracture were treated with closed reduction and percutaneous pin external fixation, among them 121 cases were followed up for more than 1 year, including 31 cases in traditional group, 12 males and 19 females, aged 45 to 74(65.4±8.4) years;90 cases in modified group, 39 males and 51 females, aged 12 to 75 (64.5±7.8) years. In traditional group, the first needle was put on the femoral talus, the second and third needles were put under the tension line, and the three needles were not on the same line in the lateral phase; in modified group, the first needle was drilled into the lateralcortex of the femur, obliquely penetrating the distal and proximal end of the femoral talus fracture, and the other two needles were drilled into the medial cortex of the femoral neck and the femoral talus, respectively. The operation time, hospital stay, postoperative ambulation time, femoral neck shortening rate, fracture healing time, fracture healing rate and femoral head necrosis rate of the two groups were observed and compared. Harris hip function score was used one year after operation.@*RESULTS@#These 121 patients were followed-up, the follow up time of traditional group was 13 to 45(30.5±11.4) months;the follow-up time of modified group was 14 to 120(34.5±12.5) months. There was no significant difference in operation time, hospital stay and femoral head necrosis rate between two groups (@*CONCLUSION@#Compared with the traditional group, the modified group has the advantages of lower femoral neck shortening rate, shorter fracture healing time, higher fracture healing rate and higher Harris hip function score.

ABSTRACT

OBJECTIVE@#To investigate the related factors of aseptic necrosis of femoral head after closed reduction and internal fixation of femoral neck fracture.@*METHODS@#From January 2009 to January 2016, 236 patients with femoral neck fracture were treated with closed reduction and internal fixation with 3 hollow lag screws, including 111 males and 125 females, aged from 19 to 89 (50.17±12.88) years. According to the follow-up results, the correlation of aseptic necrosis of femoral head was analyzed. Univariate analysis of age, gender, injured side, body weight, injury mechanism, preoperative waiting time, Garden classification and whether there was comminution of femoral neck cortex was conducted to obtain the independent variables with significant difference. Then binary logistic regression analysis was conducted to explore the independent risk factors of avascular necrosis of femoral head.@*RESULTS@#The average follow-up period of 236 cases was 4.58 years. There were significant differences in the range of injury (24.69% vs. 5.16%, @*CONCLUSION@#High energy injury, preoperative waiting time (>48 h) and comminution of femoral neck cortex were independent risk factors for aseptic necrosis of femoral head. In addition, cortical comminution on the pressure side and tension side of the femoral neck is a strong prognostic risk factor for aseptic necrosis of the femoral head, because it indicates a more serious and complex injury mechanism.
